Abearing strip 5IV formed of sheetmetal, isy mounted in the forward central portion Vof, channel 46 in drawer track 45 forbearing engagement,

on roller A31 so that the weight ofthe drawer` and its contents will be applied `through draw'erftrack 45 to intermediatetrack .20 through roller 31 and the bearing contactA of bearingr strip 5,I,thereon.

Bearing strip 5I is `mounted in the bottom of` channel 46 and is appliedin position, in the manner that bearing strip I8 is` applied to vrcasing, track II, as illustrated in Figs. 8 land @and de? scribed above. Wood screws 52, as shown'in Fig.

The cabinet and drawers are constru'ctetl t that the drawer will voccupy ,substantially` theentire depth of` thecabinet Ifrom front to` rear, las shown in Fig.,l for` example, in order toavoid i waste spacein the cabinet to the greatest extent that is practically possible, ,Therefore,, the drawer in closedpositionwill have the rear end terminate in `close adjacentrelation; from they inside face of` rearwall `3, as shown in Fig.y l.` The upper :and lowercasing, yintermediate and` drawer tracks are `constructed and proportioned tol-lt within the4 cabinet-.fand extend from the` front to the rear ends thereof, `in themanner shown in Fig. l, with the parts so arrangedthat in the withdrawn 4position thedrawer will be supported in substantially fully extended position in front of the cabinet.

There isa slight -tiltingof` drawer track 45 relative tointermediate `track 2l]` in the operation of the drawer guide` due to the clearances between the several tracks and the in' tervening and interengaged supporting rollers,` stop and guide blocks. 1 .Y

part of the drawer guide structure. 1 1

In forward movement of the drawer andinter-` mediate tracks in the operation of the drawer from a closed position, as shown in Fig.v l1,` to ,the

open position shown in Fig. 2roller 31k will travel.

from the position illustrated in Fig.l to that shown in Fig. 2. It moves `from a position adja-` cent stop block 34forwardly in the opening vmovement of the drawer until the drawer reaches the open position shown in Fig. 2'where it is` adja1 cent stop block 3| when stop and 'guide blockFDI engagesA stop block 34 to limit;` further forwardmovement ofthe drawer relative to intermediate track 20. In this position of the parts the,A ,weight` of the drawer causes the front end to fulcrurn` about roller 31 for movement in a downward di rection, :while the rear end of thevdrawer tendsito move upwardly and maintains guide block 41l in engagement with casing track IIJ lwhen the't disposed forwardly of rollers 31.

greater portion of the weight in the drawer` is `In this operation of the drawer guide intermediay `ate track 20 moves `from the rearmost positiongas shown in Fig. l, to the positionshown inFigL 21,' where the forward end extends outwardly from the 'front of the cabinet so that/'about loalf'ofin`` termediate track 20 projects vin front of the cabek inet. The intermediate track 20 is operable vin,

dependently of the motion of drawer guide 45 bef` tween its outer and innerlimits of movement. The

weight of the drawer transmitted thereto by the drawertrack through roller 31 provides for lthe support of the weight of the drawer by intermediate track 20 on the forward end portion thereby` tending to` rock intermediate track20 about bear;

ing rollers 24 to move the `front end `in `a downward direction and the rear end inan upwardV di` rection. This will cause bearing roller 29 tohave Ibearing engagement throughout the major por tion of the travel of the intermediate track with upper casing track I0 at the bottom of channel" I 2 therein. y

Whenever `the weight in thedrawer issuchthat the center of` gravity passes to the rear vof roller 31 and rollers Y2'4, then the' lrear ends ofY drawer guides 45Land. intermediate track 2l! .will drop downwardly about rollers l.31.and124as a fulcrum untilguide-and stop blocks A26 and 50'respectively, support the rear ends of the tracks-foneon` another and lower ycasing track II, in the manner shown in Fig. 1. .This condition willoccur when-the drawer, drawer track45 and intermediate track'20 lation "between the drawer,-in termediate and casing tracks where the front ends'off-the drawer and intermediate tracksare moved downwardly to the limit of clearance. This condition varies as the load in the drawer-varies becausev papers-niedin thedrawers of vfiling atthefront; V- i M1- In operation the'weight in the drawerlinbeing transmitted to intermediate track20, will'ri'ormally cause the intermediate-track tomo-ve outcabinets are always placed wardly with the 4drawer inthe ini-tial outward movement of the drawer toward open position un-` til stop -andguide block 2B engages' stopbloklt.

Then'the drawer is further moved toward and to its outermost position on intermediate track 20 while it remains stationary at its outermost limitof movement. `The frictional relation between the 'drawer track and intermediate track 20 and the manner of distributing the weight of the drawer through theseftracks to casing-'tracks IIland II will normally obtain the outward movement of the intermediate' track with the drawer track as above described, although a` change-in condition of friction andyweight position or cen-l ter of gravity in thedrawermay obtain only par-'f .tial outward movement of-intermediate track'2IJ with the drawer `or none at all, before guide and stop block 5D engages stop 34`and positively moves intermediate'track'ZU to its outermost position.

Guide block 41,' drawer'track 45, guide and stop broek su andmujer 31 'Operating in the channels of upper casing trackl and intermediate track `cooperate to interlock drawer track45 and intermediatey track 26 between upper and lower casing tracks Ill and II so thatthey cannot become disengaged in the normal'loperatio-n ofa drawer into' and out of thehoused position in the cabinet.

Guide and stop blocks 2-6, stop blocks I5 and I6v and rollers 24 running inchannels I3 and 22, also cooperate in this interlocking action for retaining the drawer and intermediate tracks engaged between thecasing tracks so that they have only forward and rearward 'movement The proportioning and arrangement of the parts provide forfree and easy operation of the drawer between its forward and housed'positions relative to thecas-v ing or cabinet. I

-Should itY be desired to remove a drawer from the cabinet, it is necessaryto moveV the drawer tof the open position .shownin Fig. 2. Then, by ele Vating' the frontend of the drawer to disengage drawer tracks 45 from roller 31 and stopblocks 3-I and 34, stop and guidel blocks 5D will then supagesasoe port the rear end of the drawer so that guide block 41 will move downwardly away from casing track I0 out of channel I2. The drawer ycan thenbe lifted vso that stop block 50 will'clear stop Ablock 34 and the drawer removed from support on intermediate tracks 20. i

Should it 'then be desired to disengage and remove an intermediate track 20 lfrom assembly with casing tracks I0 and 5I I, it is necessary to then tilt the front end of intermedi-ate track 20 upwardly to the `position shown in Fig, v6. This has a similar result to the tilting of the drawer track in disengaging bearing roller 2'9 from. channel I2 of casing track Ill. Then intermediate track l2l) may have the upper edge tiltedinwardly to rdiser'igage roller I2 from casing track .I0 through sidewise tilting motion, whereupon the intermediate track may be lifted out of engagement with lower casing track Il to completely disengage and remove it from the cabinet.

In assembling the Vintermediate track with the casing tracks, the above operation is reversed in a manner that should be clearly apparent `from the above description. 'The assemblyoffthe draw; e1' with the drawer tracks should also :beclear as the operation in assembly is `the reverse of the removal operation above described.'-

By reference to Figs. 3 to 5 itwill be seen that this drawer guide construction provides for the use of wood in providing a vmost eflicient, easyoperating and long-wearing drawer guide constructi-on'that utilizes little space thereby saving floor space. `Actual tests in the operation of the 'drawer guide constructed as shown in the drawings have produced information lshowing that lit will outwear most of the previously known drawer' guide structures made of metal, as welll as" the previous'Woocl types. with an ease comparable with metal drawer guides of the type previously known in the arta's 'well as previously known drawer guides made of wood.
